交换机IRF的mad检测可以在三层口上配置吗？可以的话怎么配置

您好，请知：

关于IRF的检测，可以配置IRF BFD检测，可参考如下配置脚本：

1.9  IRF典型配置举例

1.9.1  IRF典型配置举例（LACP MAD检测方式）

1. 组网需求

如图1-13所示，配置Device A和Device B组成IRF设备。由于IRF到中间设备Device C有跨成员设备的聚合链路，且Device C为支持LACP协议的H3C设备，我们配置LACP MAD进行分裂检测。

2. 组网图

3. 配置步骤

(1)     配置Device A

# 配置Device A的成员编号为1，创建IRF端口2，并将它与物理端口Ten-GigabitEthernet2/0/1和Ten-GigabitEthernet3/0/1绑定。

<Sysname> system-view

[Sysname] irf member 1

[Sysname] irf-port 2

[Sysname-irf-port2] port group interface ten-gigabitethernet 2/0/1

[Sysname-irf-port2] port group interface ten-gigabitethernet 3/0/1

[Sysname-irf-port2] quit

# 将当前配置保存到下次启动配置文件。

[Sysname] quit

<Sysname> save

# 将设备的运行模式切换到IRF模式。

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot.

You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Saved the current configuration to mainboard device successfully.

Slot 1:

Save next configuration file successfully.

Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

设备重启后Device A组成了只有一台成员设备的IRF。

(2)     配置Device B

# 配置Device B的成员编号为2，创建IRF端口1，并将它与物理端口Ten-GigabitEthernet2/0/1和Ten-GigabitEthernet3/0/1绑定。

<Sysname> system-view

[Sysname] irf member 2

[Sysname] irf-port 1

[Sysname-irf-port1] port group interface ten-gigabitethernet 2/0/1

[Sysname-irf-port1] port group interface ten-gigabitethernet 3/0/1

[Sysname-irf-port1] quit

# 将当前配置保存到下次启动配置文件。

[Sysname] quit

<Sysname> save

# 参照图1-13进行物理连线。

# 将设备的运行模式切换到IRF模式。

<Sysname> system-view

[Sysname] chassis convert mode irf

The device will switch to IRF mode and reboot.

You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Saved the current configuration to mainboard device successfully.

Slot 1:

Save next configuration file successfully.

Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

设备B重启后与设备A形成IRF。

(3)     配置LACP MAD检测

# 设置IRF域编号为1。

<Sysname> system-view

[Sysname] irf domain 1

# 创建一个动态聚合接口，并开启LACP MAD检测功能。

[Sysname] interface route-aggregation 2

[Sysname-Route-Aggregation2] link-aggregation mode dynamic

[Sysname-Route-Aggregation2] mad enable

You need to assign a domain ID (range: 0-4294967295)

[Current domain is: 1]:

The assigned domain ID is: 1

MAD LACP only enable on dynamic aggregation interface.

[Sysname-Route-Aggregation2] quit

# 在聚合接口中添加成员端口Ten-GigabitEthernet 1/2/0/2和Ten-GigabitEthernet 2/2/0/2，专用于Device A和Device B实现LACP MAD检测。

[Sysname] interface ten-gigabitethernet 1/2/0/2

[Sysname-Ten-GigabitEthernet1/2/0/2] port link-aggregation group 2

[Sysname-Ten-GigabitEthernet1/2/0/2] quit

[Sysname] interface ten-gigabitethernet 2/2/0/2

[Sysname-Ten-GigabitEthernet2/2/0/2] port link-aggregation group 2

(4)     配置中间设备Device C

 

Device C作为中间设备来转发、处理LACP协议报文，协助Device A和Device B进行多Active检测。从节约成本的角度考虑，使用一台支持LACP协议扩展功能的设备即可。

# 创建一个动态聚合接口。

<Sysname> system-view

[Sysname] interface route-aggregation 2

[Sysname-Route-Aggregation2] link-aggregation mode dynamic

[Sysname-Route-Aggregation2] quit

# 在聚合接口中添加成员端口Ten-GigabitEthernet1/0/1和Ten-GigabitEthernet1/0/2，用于帮助LACP MAD检测。

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] port link-aggregation group 2

[Sysname-Ten-GigabitEthernet1/0/1] quit

[Sysname] interface ten-gigabitethernet 1/0/2

[Sysname-Ten-GigabitEthernet1/0/2] port link-aggregation group 2
